Physical Therapy School with low gpa

I just graduated with a 2.9 undergrad gpa with a Bachelors in Kinesiology: Exercise Science. I know that it is a pretty low gpa and would not have a chance to get into a DPT program right now. In order to raise my overall gpa, do I need to take post bacc classes or just retake prerequisites at a community college. I still need to to a physics, bio, chem, and psychology but might retake anatomy and phys to get better grades. I also just got a job as a PT Aide to get the hours necessary. So my main question is whether I should just take prerequisites at a community college or go back to a post bacc program to raise my undergrad gpa?
